The DDR2 Joker Upgrades GeForce 6600

Overclocking

The NVIDIA reference design standard is 350 MHz core and 800 MHz (DDR) for the memory. XFX was already pushing the core 50 MHz over spec, but we were able to get the card's core up to 537 MHz and the memory up to 988 MHz (DDR). That is a 23.5% overclock on the memory and an astounding 34% overclock on the core. This let us obtain a score of 3,678 using the default settings in 3DMark 2005, which is a 23.8% score increase. This is very nice result for a user that wants to overclock the card to yield higher frame rates.
